SPECIFICATION forming part of Letters Patent No. 678,652, dated July 16,1901.

Application filed January 29,1901. Serial No. 45,254. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY FRANKLIN FAR- LEY, a citizen of the UnitedStates, and a resident of Kalona, in the county of Washington 5 andState of Iowa, have invented a new and Improved Rotary Engine, of whichthe follow ing is a full, clear, and exact description.

The object of the invention is to provide a new and improved rotaryengine which is simple and durable in construction, very ef: fective inoperation, and arranged to permit of convenient reversing and ofutilizing the motive agent to the fullest advantage.

The invention consists of novel features I and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews- Figure 1 is an end elevation of the improveinent. Fig. 2 is atransverse sectional side elevation of the same. Fig. 3 is a sectionalside elevation of the same on the line 3 3 in Fig. 1. Fig. 4 is asectional plan view of the same on the line 4 4 in Fig. 1. Fig. 5 is aperspective view'of one of the abutments, and 0 Fig. 6 is a face view ofthe exhaust-valve.

The cylinder A is mounted on a suitablyconstructed base B, and in thecylinder-heads is journaled the main driving-shaft O, carry ing a pistonD concentric with the cylinder 3 5 and provided with piston-heads E E,located diametrically opposite each other and mounted to slide inrecesses formed in the piston D, springs E pressing the saidpiston-heads outwardly to hold their outer ends in contact 0 with theinner surface of the cylinder A. On opposite sides of the piston D arearranged abutments F F, of which only one is active at a time, eachabutment when in use forming a supply-chest of the motive agent for thecylinder, as hereinafter more fully described. The abutments F F aremade hollow for this purpose and are fulcrumed on supply-pipes G G,extending to the outside of the cylinder and connected with a mainsupply-pipe G leading to a boiler or other suitable source ofmotive-agent supply. The ends of the pipes G G within the cylinder areperforated,

as shown in Fig. 4, so that the motive agent can pass from the pipesinto the hollow abutments F FQ ments F F are formed with openings Fthrough which passes the motive agent into the cylinder to rotate thepiston D.

When the abutment F is in use, as shown in Fig. 2, then the motive agentpassing into the cylinder acts successively on the heads E E to turn thepiston D in the direction of the arrow a. When it is desired to reversethe engine, the abutment F is moved outward into a recess A, formed inthe cylinder A, while the other abutment F is moved from its recess Ainto the cylinder, so as to become the active abutment, and then themotive agent passing from this abutment F into the cylinder acts on thepiston-heads E E to ro- 7o tate the piston D in the inverse direction ofthe arrow a. The under sides of the abutments F F are curved, as isplainly indicated in Fig. 2, so that when the piston-head E or E comesin contact with the said under side then the corresponding piston-headis pushed inward against the tension of its spring E to pass theabutment, and as soon as this takes place the spring E again forces thecorresponding abutment outward to take steam.

The abutments F F are simultaneously moved by mechanism under thecontrol of the operator-that is, when one abutment moves into an activeposition the other moves out of an active position. For the purposedescribed the abutments are provided with stems H H, extending throughthe walls of the recesses A A to the outside of the cylinder, andtheouter ends of the said stems H H are connected by links I I withalever 0 J, fulcrumed on the driving-shaft O and provided with a handlocking device J adapted to engage a notched segment J secured on thecylinder-head. When the'operator unlocks the lever J and swings the samefrom the left to the right to the position shown in Fig. 3, then theabutment F is moved into an active position, while the abutment F ismoved into an inactive position--that is, outward into the recess A.When the lever J too is swung from the right to the left, then theabutment F is swung inward into an active The forward ends of the abut-55 position, while the abutment F is swung out-- ward into its recess Ato become inactive.

In order to control the amount of motive agent passing from theabutments F F into the cylinder at the time an abutment is in aninactive position, I provide slide-valves K K over the openings F of theabutments, and said slide-valves are provided with stems K K each ofwhich carries at its outer end an adjustable collar K connected by alink L with a lever L, fulcrumed on a bracket N, attached to the,corresponding stem H or H of the abutments F or F. L is connected by alink L with a hand-lever 0, having a locking device 0, adapted to engagea segment P, pivotally connected with said bracket N, and with a link P,fulcrumed on the cylinder A, as is plainly shown in Figs. 1 and 2. Thelever O is fulcrumed on the se ment P, and the latter moves with thecorresponding bracket N when the abutments F F are shifted by theoperator manipulating the lever J, as above described.

By the operator operating the hand-lever O a swinging motion is given tothe lever L, which by the link L and collar K imparts a sliding motionto the corresponding valve K or K, so as to shift the same relatively tothe opening F to allow more or less motive agent to pass into thecylinder A, according to the direction in which the hand-lever O isshifted.

The exhaust in front of a pistonhead takes place through an exhaust-porta, formed in a circular valve R,,(see Figs. 3 and 6,) extending betweenthe front face of the piston D and the cylinder-head A and mounted toturn loosely on the shaft 0. The port oregisters with a segmentalexhaust-channel Q, formed on the inner side of the cylinder-head A andleading to an exhaust-pipe Q, as is plainly indicated in Figs. 1 and Theexhaust-valve R is connected with a hand-lever S, fulcrumed on one ofthe cylinder-heads by means of a pin S, extending through a segmentalslot S formed in said head A of the cylinder. The lever S is providedwith a locking device S for locking the lever on a segment S and holdingthe valve R in the desired position-that is, with its port 0. either atthe right or the left portion of the exhaustchannel Q. When the abutmentF is in use, the valve R closes the left-hand half of theexhaust-channel Q, and when the abutment F is in active position thenthe operator has to shift the valve R to bring the port a to theright-hand half portion of the channel Q.

A packing and an adjusting disk T is arranged between the cylinder-headA and the rear face of the piston D, and set-screws T, screwing in saidhead, serve to adjust the disk transversely to hold the piston in propercontact with the exhaust-valve and prevent leakage of steam.
